Such as smart watches, bracelets, light bulbs, desk lamps, hot water bottles, cameras, driving recorders, rice cookers and so on. Most of these products are labeled as "smart".
Therefore, netizens expect Xiaomi to be smarter, and sometimes they joke about "Xiaomi smart contraceptive stick" and the like.
The netizens, who don't know who took the lead, like to post "Xiaomi Smart XX" at the top of the video uploaded by Xiaomi Company (XX is the object in the current picture or the ending word of the current advertisement), which is purely ridiculous.
Similarly, there is "the first XX for young people".
"Young people's first mobile phone" is an advertising word that Xiaomi used on the red rice mobile phone before. Later, it was also used by netizens to ridicule and joke. For example, when Xiaomi releases things like balance cars and Mijia scooters, someone will vomit "the first car accident of young people".
This is my understanding, I hope I can help you!
